has the solutionSugar Level Testing -
How it WorksThese precision digital refractometers measure the light refracted from a sample without the need for a separate light source or worry about sample temperatures.
All they need are a couple of drops of the sample
on the sample well prism and a single key to be pressed. A yellow LED light is then shone through the prism up through the sample and the light refracted back is focused onto a precision CCD sensor which provides a highly accurate result displayed on the large easy to read LCD display.
What is Brix?Degrees Brix (symbol °Bx) is a measurement of the mass ratio of dissolved sugar to water in a liquid. A 25 °Bx solution is 25 % (w/w), there is 25 grams of sucrose sugar and 75 grams of water in the 100 grams of solution.

the Digital advantage at a Mechanical PriceFor the same price or less than a traditional analog refractometer our new digital meters provide laboratory grade analysis of sugar content yet are simple and quick to use.Calibration is easy and does not require the use of special calibration solutions. Simply place a couple of drops of pure water on the sample cell and press a button – the meter will automatically calibrate and be ready to use in less than 2 seconds.Hanna digital refractometers are designed for either lab, factory or field use and are fully sealed against the ingress of water or dust to make them a real go anywhere meter.Whichever meter you choose, results are shown directly converted to %sugars by weight concentration (or directly in %Brix on the HI96801) together with the temperature of the sample.
